Van driver Jeetandra Dadral, 34, from Handsworth Wood, Birmingham died at the scene from his injuries.

The IPCC was informed shortly after the incident and subsequently declared an independent investigation. IPCC investigators have now launched a witness appeal for anyone who may have been in the area at the time.

Anyone who may have witnessed the incident or events leading up to it is asked to email Lutterworth@ipcc.gsi.gov.uk or call 0800 092 2434.

IPCC Commissioner Derrick Campbell said: “Our investigation will examine the actions of the drivers and the events that took place. I would urge anyone with information or who may have seen anything that night to contact us and help with our enquiries.”
